Subject: [PATCH 1/2] crypto: ccp - Use only the relevant interrupt bits
Date: Wed, 12 Apr 2017 17:54:35 -0500 [thread overview]
Message-ID: <20170412225435.17707.67228.stgit@taos> (raw)
In-Reply-To: <20170412225324.17707.75176.stgit@taos>
Each CCP queue can product interrupts for 4 conditions:
operation complete, queue empty, error, and queue stopped.
This driver only works with completion and error events.
